Abstract (en)
[origin: EP3785945A1] An object of the present invention is to lower a coefficient of friction of the sidewall surface to reduce the friction between the tire sidewall and the curb stone, thereby enabling one to suppress the abrasion of the tire sidewall due to curb stone rubbing and also enabling one to use the tire for a long period of time. Provided is a tire prepared by attaching a vulcanized rubber body of a rubber composition containing a fatty acid amide onto the outer surface of a sidewall thereof.
